This force calculator can help you calculate the force, mass or acceleration in multiple measurement units if you know any 2 variables from Newton's Second Law of Motion.

Instruction: Please input only 2 out of the 3 fields available to find the desired one!

Mass:*
Acceleration:*
Force:*

## How does this force calculator work?

In physics, force can be defined as an interaction with both magnitude and direction that, when unopposed, will have an impact on the motion/velocity of a given object having mass. It is denoted with “F” and in the SI is measured in Newton (N).

According to the Newton's Second Law of Motion it can be expressed as a mathematical equation as:

Force (F) = Mass (m) * Acceleration (a)

This force calculator can compute any variable from the above equation if two figures are provided:

■ In case the mass and acceleration are given it will calculate and display the force by using the standard formula:

F = m * a

■ If the mass and force are known it will determine the acceleration by applying this equation:

a = F/m

■ When force and acceleration are provided it will estimate the mass:

m = F/a

Please note that each of the three variables can be specified in any measure from the drop down lists available, while they are by default set up in the SI units:

■ Mass is by default in kg, while the other measurement units available and their conversion rates are explained in the next rows:

 Convert from: To kg: kg 1 g 0.001 Pound 0.45359237 Ounce(Oz) 0.028349523 Stone 6.35029318 ton 1000 mg 0.000001 ug 0.000000001 ng 0.000000000001 pg 0.000000000000001 Carat(metric) 0.0002 Grain 0.0000648 Dram 0.001771845

■ Acceleration is by default expressed in meters per square second (m/s2) but there are other measurement units available to choose from:

 Convert from: To meters per square second (m/s2): m/s2 1 Km/s2 1000 Mile/h2 0.000124178 Km/h2 0.00007716 dm/s2 0.1 cm/s2 0.01 mm/s2 0.001 Mile/s2 1609.344 Yard/s2 0.9914 Foot/s2 0.3048 Inch/s2 0.0254

■ Force is by default set up in Newton (N) while the user can opt out to input it in any of the following units:

 Convert from: To Newton (N): N 1 kN 1000 mN 0.001 uN 0.000001 nN 0.000000001 pN 0.000000000001
